.UPDATE...
Issued at 830 PM EDT Mon Sep 15 2025

Mostly quiet conditions locally this evening aside from a cluster
of showers that has blossomed over the interior across parts of
Polk, Hardee and Highlands counties as a result of a westward-
moving outflow boundary from earlier ECFL convection. A few
additional showers are possible in association with the boundary
through the evening as it continues westward before gradually
winding down tonight. Mostly clear to partly cloudy skies tonight
with lows from the mid to upper 60s north to the lower to mid 70s
central and south.

Drier air continues to sit over the area giving us quiet and
slightly cooler weather especially north of I-4. There is just
enough moisture down in SW Florida to produce a shower or two but
most of us will be staying dry today.

As we go through the rest of the week there will be a divide between
more moist air, rain showers, and summer time temperatures to the
south. While the the northern area of our CWA has drier air, less
rain, and slightly cooler air. A great example of this divide is
Thursday and Friday where the Nature Coast has PoPs between 10 to 20
percent while SW Florida are sitting at 60 to 70 percent.

As we get into the weekend moisture will start to return to the the
Nature Coast with the best chance for showers across the whole CWA
